A damper disc disposing a pair of integrally interconnected side plates on both sides of an annular flange of a hub, interconnecting the side plate and the flange by means of a torsion spring, and interposing a friction member between an inner peripheral part of the annular flange and an inner peripheral part of the side plate; a friction plate and a wave spring being interposed in layers as friction members in either or both of between the annular flange and the both side plates, the friction plate being rotatably fixed to any one of the annular flange and the side plate and the wave spring being rotatably fixed to the other of them, and a mating surface of the friction plate on the side of the wave spring being formed into a waved surface corresponding to the wave spring.
